hi my daughter is 4 year old,for the past 5 days in some mid might or early morning she wakeup to sneeze and sneeze continuosly atleast for 15 times with clear white discharge from her nose,may I know the reason?

A. during winter season if maybe is not covered properly at night feeling cold when they get up in morning they may feels sneezing more constantly so not to very much worry about this and just wear proper clothings for the baby according to the temperature
